Door Sill vs Threshold: Quick Answer<\/h2>

A door sill and a door threshold are closely related, but they are not the same part. The door sill is the bottom structural part of the door frame that sits on the subfloor or foundation and supports the doorway. The threshold is the strip installed on top of the sill, designed to seal the gap under the door and create a transition between interior and exterior flooring. In short, the sill provides structural support, while the threshold improves sealing, weather protection, and daily usability.<\/p>
